FIELD: agriculture.

SUBSTANCE: method comprises adding to the basic diet of agent of increasing the reproductive qualities at a dose of 0.3% of the weight of daily rate of feed in the first 84 days of pregnancy and at a dose of 0.4% from the 85^th day to 115^th day of pregnancy, 100 g of which contains: Vitamin A (retinol acetate) - 100 thous.
